Coffee lovers, alert! A new report says that the world's coffee supply may be in danger owing to climate change. In the world's biggest coffee-producing nation, Brazil, the effects of warming temperatures are already being felt in some communities.

When the test scores came out, Lucas Siqueira, 27, was really excited. His high mark on the Foreign Service exam earned him a coveted position at Brazil's highly competitive Ministry of Foreign Affairs.

"They hire 30 diplomats a year and thousands of people sign up," he says in fluent English from his home in the capital Brasilia.

It was, he says, a great day.

Siqueira considers himself to be mixed race, known in Brazil as pardo, or brown.

No one would want to throw the biggest party in the world if they were in the middle of divorce, broke and being audited.

That's pretty much the situation Brazil finds itself in right now, during the Summer Olympic Games.

President Dilma Rousseff is in the midst of being impeached. Her trial starts in a few days, after the end of the games. The country is going through a historic recession and budgets are being repeatedly slashed. And the largest corruption investigation in Latin American history has taken down politicians and captains of industry alike.

"That bullet almost hit my bed. Have mercy, please God, deliver us," a resident in a group of Rio favelas called Alemao said in a message posted Saturday on the WhatsApp smartphone messaging service.

While media attention has focused on U.S. Olympic swimmer Ryan Lochte and three other U.S. swimmers who were robbed at gunpoint on Sunday, violence is surging in Rio's favelas, or shantytowns, far from the games.

And that is exactly the way internationally famous chef Massimo Bottura wants it. The aim of this new venture, though, is different: It's a gourmet soup kitchen that uses leftovers to feed the less fortunate.

When you walk into Bottura's latest culinary temple, it would not be out of place in his home city of Modena, Italy, the location of his Michelin three-star restaurant Osteria Francescana.

Brazil's suspended President Dilma Rousseff's fate seems to be all but sealed.

Senators voted overwhelmingly to try the suspended leader, 59-21, in the last leg of the process to remove her from office. She will now face a trial in the Senate over alleged fiscal mismanagement. A final vote after all the evidence has been presented and weighed is set to take place at the end of the month.

On the day she was killed, Alexsandra Moreira thought she was safe. She thought she had managed to break away and protect herself.

Her brother even escorted her to the bus station that morning to make sure she was OK on her way to work.

"When she got on the bus, my brother told her, 'If anything happens, just call me.' Ten minutes later, his phone rang and it was her. All he could hear was her screaming, pleading for help," Moreira's sister, Andreza da Silva, says.

As Venezuela unravels — with shortages of food and medicine, as well as runaway inflation — President Nicolas Maduro is increasingly unpopular. But he's still holding onto power.

"The truth in Venezuela is there is real hunger. We are hungry," says a man who has invited me into his house in the northwestern city of Maracaibo, but doesn't want his name used for fear of reprisals by the government.

The wiry man paces angrily as he speaks. It wasn't always this way, he says, showing how loose his pants are now.

Fed up with a collapsing economy, Venezuelans have been turning out in huge numbers this week to support a referendum that could potentially end the rule of President Nicolas Maduro and his Socialist Party.

The opposition has to collect hundreds of thousands of signatures as the first step in a complicated process leading to a recall vote on ousting Maduro. The electoral authority gave the opposition five days to verify the signatures. The deadline is Friday, and it's a race against time for both the opposition and the president.

In the misty rain, surrounded by Rio de Janeiro's green hills, police officer Eduardo Dias was buried last week. He was shot, purportedly by gang members, as he was leaving his post inside the favela, or shantytown, where he worked as a community cop.

The killing took place a few hundred feet from the Maracana Stadium, where the opening ceremony of the Summer Olympics will be held on Aug. 5. As family members wept by the graveside, the pastor raised his hands.

Amid all the upheaval in Brazil, women have suddenly become much less prominent at the top levels of government, and this hasn't escaped the notice of social media.

The country's first female president, Dilma Rousseff, was suspended from her post after a marathon session in the Senate that concluded early Thursday. She now faces an impeachment trial that could last months.

The man replacing her on an interim basis, Michel Temer, who had been the vice president, quickly announced his Cabinet picks. There wasn't a woman among them.

Three years ago, NPR visited the port of Suape outside the northern Brazilian city of Recife when it was an example of Brazil's booming economy. Brazil's state oil company, Petrobras, has a large refinery that was working full tilt.

That's the story that Jailson Correia tells. He's the health secretary for Recife, the city with the most cases of brain damage in infants linked to Zika. The virus began sweeping through Brazil last fall. In November, concerned about the scope of the outbreak, he asked the federal government for help. What they gave was a drop in the bucket.
